Not 2 amps, more like 1.3 amps before it shuts down. Did not damage the board, it recovers from OC
Could not get 2 amps through the board boosting from 5v to 12v. The board shut down at 1.4 amps. It does not get very warm, so the shutdown had to be in the design. I don't know where they got the 2 amp rating. It might be that at certain voltages, it might be able to get two amps, but that is not what is advertised. I could not get two amps through it no matter how I adjusted it.

Poor quality, but it can work if you know not to put too much pressure in either direction.
Of poor quality, you get what you pay for, so in a pinch, these are ok, but there are others that have a much smoother movement, and repeatable readings. These don't always give the same reading because they are not made to a tight tolerance. If you put minimal pressure on the jaws in reverse, you can get a negative number? How could that be possible, I can't do that with other calipers, zero is zero, and there is no way to get less than zero. So the general function can work, you just should not put too much pressure on it because it will flex and through your reading off.

Works well for what I use it for.
I bought this to program Atmel controllers and it did it with no problem. It supports a wide range of chips, but I have not tried it on others.
